Hi Roy
The brilliance and pattern style certainly looks right for ABP / APC.
I see no grey (unpolished) cutting which would indicate more recent manufacture but as to actual age and whether it is from America or not, I cannot help.
This style of glass went out of fashion very suddenly in the early part of the time of WWI. Reproduction
to the same standard would be very very costly.
I am given to understand that identifying precise makers, in the absence of marks, is often extremely difficult and sometimes impossible as the cutters all copied each others patterns and the range of motifs is, in any case, limted.

American Brilliant Period Cut Glass, 1876 – 1917 by John, C. Roesel at

Terry, Leni and others will hopefully be able to help more.
